WAGON-BOLSTER.

SPECIFICATION forming part of Letters Patent No. 417,899, dated December24, 1889.

Application filed September 26, 1889. Serial No. 325,150, (No model.)

.To all whom it may concern:

Be it known that I, EDWARD W. BENNETT, a citizen of the United States,residing at Southampton, in the county of Suffolk and State of New York,have invented certain new and useful Improvements in 'WagonJSolsters, ofwhich the following is a full and clear description, reference being hadto the accompanying drawing, forming part of this specification, inwhich the figure is a sectional view showing a hollow bolster with metalstakes.

My invention relates to certain new and useful improvements in bolstersfor vehicles, and especially lumber-wagons; and it consists in thepeculiar construction and combination of parts, which I shallhereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I willnow describe its construction and indicate the manner in which the sameis carried out.

In the accompanying drawings, A repre sents a metallic wagon-bolsterprovided with any Well-known form of metal stakes a formed integraltherewith. This bolster is hollow, and is open at top and bottom, or, inother words, is formed with aninternal chamber-B, which extends nearlyits whole length. Within the chamber thus formed is placed a spring orcushion 0, here shown as being a semi-elliptical leaf -spring with itsends mounted 011 pins 1), which pass transversely through the bolsternear the ends thereof, as shown in Fig. 1. The central bowed portion ofthe spring or cushion 0, when the vehicle is not loaded, projectssomewhat above the top of the bolster, and has secured to it thetransverse beam D, upon which the weight or the vehicle-body rests; butwhen a heavy load is placed on the wagon this spring is depressed intothe hollow bolster to permit the transverse beam D to enter the open topof the bolster until its top surface is flush with the top of thebolster, whereby the weight is removed from the transverse beam andtransferred directly to the bolster. The spring is directly over theaxle of the vehicle, and as said spring is permitted to be pressed intothe hollow bolster it is evident I am enabled to construct a vehiclewith the body as low as possible, as the space usually occupied by thesprings, which rest directly upon the top of the bolster, is not needed.If the vehicle is only slightly loaded, the spring will not be forcedinto the hollow bolster, but will serve as an easy bearing for the bodyof the vehicle, thereby making the riding comfortable to the occupants,and at the same time the rattling noise incident to springs secureddirectly on top of the bolster is avoided.

A bolster when constructed as before described, is cheap and durable,and the strain upon the spring is removed by reason of the said springbeing permitted to enter the bolster.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

An improved wagon-bolster consisting of a hollow casing provided withintegral end stakes, abeam extending longitudinally of the bolsterbetween its stakes, a single semi-elliptical spring secured at itscenter to the central part of the transverse beam, and pins passingthrough the ends of the spring and through the sides of the casing, asherein described.

EDWARD WV. BENNETT.
